Industrial silicone tubing has become an essential component across industries ranging from pharmaceuticals and food processing to medical devices, chemical processing, automotive, and laboratory equipment. Its exceptional flexibility, temperature resistance, chemical stability, and long service life make it one of the most reliable tubing materials available today.
However, not all silicone tubing is the same. Depending on the manufacturing process and intended application, silicone tubing is available in several specialized variants, including Platinum Cured Tubing, Peroxide Cured Tubing, Multi-Lumen Tubing, Spiral Reinforced Tubing, and Medical Grade Silicone Tubing. Choosing the right type ensures optimal performance, regulatory compliance, and product longevity. Manufacturers such as Silicone EngiTech produce a broad portfolio of silicone tubing solutions for industrial, pharmaceutical, food-grade, and medical applications. (Silicone EngiTech)
In this guide, we'll explain each type in detail and help you determine which silicone tubing best suits your application.
What is Industrial Silicone Tubing?
Industrial silicone tubing is an extruded flexible hose manufactured from high-quality silicone elastomers. Unlike PVC or rubber tubing, silicone remains stable across a wide temperature range while maintaining excellent flexibility and resistance to UV radiation, ozone, moisture, and many chemicals.
Key Properties
- Temperature resistance from approximately -60°C to +200°C
- Non-toxic and odorless
- Excellent flexibility
- UV and ozone resistant
- High dielectric strength
- Smooth internal surface for efficient fluid transfer
- Long service life
- Suitable for sterilization
These characteristics make silicone tubing ideal for demanding industrial environments.
Types of Industrial Silicone Tubing
1. Platinum Cured Silicone Tubing
Platinum cured tubing is manufactured using a platinum catalyst during the curing process. This results in an ultra-pure silicone product with minimal extractables and excellent transparency.

- Laboratory equipment
- Beverage processing
- Food production
Best For
Industries requiring strict hygiene standards and regulatory compliance.
2. Peroxide Cured Silicone Tubing
Peroxide cured tubing uses organic peroxide catalysts during vulcanization. It is widely used because of its cost-effectiveness while still delivering excellent mechanical properties.
Advantages
- Economical solution
- Good flexibility
- High temperature resistance
- Durable construction
- Easy fabrication
- Reliable industrial performance
Applications
- Chemical transfer
- Industrial machinery
- Vacuum systems

Best For
General industrial applications where pharmaceutical-grade purity is not required.
Platinum Cured vs Peroxide Cured Silicone Tubing
| Feature | Platinum Cured | Peroxide Cured |
|---|---|---|
| Purity | Very High | High |
| Extractables | Extremely Low | Moderate |
| Transparency | Excellent | Good |
| Cost | Higher | More Economical |
| Biocompatibility | Excellent | Limited |
| Pharmaceutical Use | Yes | Limited |
| Food Grade | Yes | Yes |
| Medical Applications | Preferred | Limited |
| General Industrial Use | Yes | Yes |
3. Multi-Lumen Silicone Tubing
Multi-lumen tubing contains two or more separate internal channels within a single tube.
Each lumen can carry different fluids, gases, wires, or sensors independently.
Benefits
- Saves installation space
- Simplifies system design
- Reduces tubing clutter
- Lightweight construction
- Improved fluid management
- Custom lumen configurations
Typical Applications
- Medical catheters
- Drug delivery systems

4. Spiral Reinforced Silicone Tubing
Also known as spiral tubing, this product includes a stainless steel or polymer reinforcement embedded inside the silicone wall.
The reinforcement prevents collapse under vacuum or pressure.
Advantages
- Higher pressure resistance
- Excellent vacuum performance
- Maintains flexibility
- Prevents kinking
- Longer operational life
- Superior mechanical strength
Applications
- Vacuum pumps
- Pharmaceutical plants
- Food processing equipment
- Chemical transfer
- Industrial fluid handling
- Dairy processing
5. Medical Grade Silicone Tubing
Medical grade tubing is manufactured using specially formulated silicone that complies with stringent healthcare standards.
It offers maximum purity and patient safety.
Features
- Biocompatible
- Non-toxic
- Sterilizable
- Flexible
- Smooth inner surface
- Excellent tear strength
- High transparency
Applications
- IV tubing
- Catheters
- Respiratory devices
- Dialysis equipment
- Surgical equipment
- Medical pumps
- Diagnostic systems
Temperature Resistance
One of silicone's biggest advantages is its impressive operating temperature range.
| Property | Typical Range |
|---|---|
| Minimum Temperature | -60°C |
| Maximum Continuous Temperature | +200°C |
| Short-Term Exposure | Up to +250°C (depending on grade) |
This makes silicone tubing suitable for both refrigeration and high-temperature processing.
Chemical Resistance
Industrial silicone tubing offers excellent resistance against:
- Water
- Steam
- UV radiation
- Ozone
- Oxygen
- Mild acids
- Mild alkalis
- Alcohols
- Cleaning chemicals
However, silicone is generally not recommended for prolonged exposure to concentrated acids, aromatic hydrocarbons, or certain petroleum-based oils.
Industries Using Silicone Tubing
Industrial silicone tubing serves numerous sectors, including:
- Pharmaceutical manufacturing
- Biotechnology
- Medical device production
- Food and beverage processing
- Dairy industry
- Chemical processing
- Laboratory research
- Automotive manufacturing
- Electrical and electronics
- Industrial automation
- Packaging machinery
- Water treatment
How to Choose the Right Silicone Tubing
When selecting silicone tubing, consider the following factors:
Operating Temperature
Ensure the tubing can withstand your process temperatures.
Pressure Requirements
Choose reinforced spiral tubing for vacuum or high-pressure applications.
Regulatory Compliance
Medical and pharmaceutical industries typically require platinum cured or medical-grade tubing.
Fluid Compatibility
Verify compatibility with the fluids, chemicals, or gases being conveyed.
Sterilization Needs
For repeated autoclaving or sterilization, platinum cured tubing is generally the preferred option.
Flexibility
Applications with tight bending radii benefit from standard silicone tubing, while demanding pressure environments may require reinforced variants.
Maintenance Tips
To maximize service life:
- Avoid sharp bends
- Clean regularly using approved cleaning agents
- Inspect periodically for wear or discoloration
- Store away from direct sunlight when not in use
- Replace tubing showing signs of hardening or damage
Why Quality Matters
Poor-quality silicone tubing can result in:
- Premature failure
- Fluid contamination
- Reduced pressure performance
- Increased maintenance costs
- Regulatory compliance issues
